Next month, Oskar Blues Brewery is celebrating National Chocolate Day by releasing a very special version of its most popular imperial stout.

Bourbon Barrel-Aged Mocha Ten Fidy is a 12.9 percent ABV imperial stout aged in bourbon barrels with Mexican cold-brewed coffee sourced from Hotbox Roasters and unsweetened pure liquid cacao from Boulder, Colo.-based Cholaca that will be packaged in 19.2-ounce cans. As the name suggests, the base beer is the Longmont, Colo.-based brewery’s Ten Fidy, a 10.5 percent ABV imperial stout.

“Ten FIDY Imperial Stout doesn’t know how to use its inside voice in the first place; and on this one, we hooked it up to a Cholaca-and-coffee amplifier and turned the volume up to 11,” said Tim Matthews, head of brewing operations for Oskar Blues, in a press release.

This will be the second Ten Fidy variant to be sold in cans in recent months, as the brewery released Barrel-Aged JahVanilla Ten Fidy on April 20, a 12.9 percent ABV imperial stout aged in bourbon barrels with vanilla and Jamaican coffee beans sourced from Hotbox Roasters.

According to a prerelease from Oskar Blues, Bourbon Barrel-Aged Mocha Ten Fidy will be packaged in 19.2-ounce cans ($15) and is being released exclusively at the brewery’s three Colorado taprooms on July 7 with a purchase limit of five cases per person.
